I have a Tecumseh H7 130205D mounted on a craftsman snowblower.

It has carb troubles. A model 110 carb is mounted (it should have a 631954). A PO managed to get it to fit. I guess it must be clogged internaly and I was hoping to avoid pulling it all apart.

A replacment 631954 (the proper carb) is $90, thats almost as much a I paid for the blower :mad:

Is there a "generic" tecumseh carb that is close enough to fit (I am not worried about the primer as this unit has electric start)?

Failing that, will the tecumseh 31840 kit rebuild my 110 carb?

If it's all there, why not just fix it? Not much too it. Most of the time the problem is the adjustable main jet assembly that pulls out the bottom. That, and a soft-sticking float-seat. Ten minutes work and $5 in parts and you might be fine.

Thanks for the reply.

The 110 is stamped on the carb itself. It is "110 oeg" I gather the last three are the date code. I could not find anything on a 110 on the tecumseh website...It must be really old, or rare.

Ill check out the oregon info and try to find one.

The pn 631954 carb is a "service carb" to replace the orig pn 631920 carb,if you don't have the orig carb the service carb will probably be of little/no use to you as complete choke assembly & throttle linkage must be reused from orig carb.try going to ebay & type oregon carb in search,this is an aftermarket brand,go thru listings & look at tecumseh carbs listed,a carb for an h/hh 60 or 70 should work on eng,you'll have to look at carb pic's to see if linkage setup will work for you.

The carb kit pn 31840 is for use on orig carb pn 631920,some/all of the parts may work with carb you have now,the only way to tell is buy kit & see what parts if any will fit carb,the float needle/needle seat are usually all the same,problem may be needle valves & bowl gasket.

Question when you say 110 for carb-is this the number stamped on carb body or is carb for a mod 110 eng?
